I need to open an environment and discover all of the databases. From what I understand, the database names are stored in the default, nameless db. But what encoding? Creating a db ends in a native method stub passing a String... UTF-8?

    Txn<ByteBuffer> txn = env.txn(null);
    env.openDbi(null).iterate(txn).forEachRemaining(kv -> {
      ByteBuffer keybytes = kv.key();
      String key = ??? 
    });

It would probably be useful to add both the ability to retrieve all dbi names to Env, as well as the ability to return all Dbis in an Env as a Map<String, Dbi>. The LMDB docs suggest that it is good practice to retrieve and re-use these anyway.

So I suppose this is mostly a question, but also a minor feature request.
